preliminary plan, architectural renderings, prepared by a registered architect, shall be submitted for all proposed buildings, together with a list and samples of types of exterior building materials that will be visible from any public street. Similarly, a rendered landscape plan, prepared by a registered landscape architect shall also be submitted for review. An outdoor lighting plan shall also be submitted for review.
(7) Township approval of proposed architectural and streetscape design is required for the land development application to be approved.
D. Site Design Standards:
(1) Overall Site Coordination: The site shall be designed as a unified development, with a coordinated site design, landscape plan, signage, wayfinding, lighting, site amenities, paving and other similar site features
(2) Location of Parking: The site shall be designed to minimize the view of parking lots from the street. Parking shall be concentrated to the side and rear of the building(s) and behind the front yard setback line.
(3) Vehicle Access: In order to facilitate efficient internal traffic circulation and minimize road traffic for short trips, all parking areas shall be designed to connect directly to parking areas on adjacent lots. If a connection is not possible at the time of land development, site design provisions shall be made for a future connection to adjacent properties. Permanent cross-access easements between properties shall be enacted. Shared or common driveways shall be provided.
a. If a lot is developed or redeveloped, any new vehicular access point shall be located along a side lot line in order to create a shared driveway with the adjacent lot.
(4) Pedestrian Circulation: A safe and direct pedestrian access shall be provided from the trails and sidewalks to the building entrances and exits.
a. When 150 feet or more of new building wall is constructed between a sidewalk or pedestrian / bicycle way and parking at the rear of the building, a pedestrian access way shall be provided (i.e., through a lobby or via an alley) from the pedestrian way to the parking facilities.
(5) Accessibility: An accessible route shall be provided for persons with disabilities in accordance with all applicable federal, state and local standards.
E. Buildings and Streetscape Design Standards: Treatments between any building and
the street edge shall utilize the following design standards:
(1) Building Orientation and Access. a. Buildings shall be designed with windows, public access points and signage
facing streets, sidewalks and pedestrian ways. b. Grade level exterior doors that swing onto a public walkway are prohibited.
(2) The Primary Building Entrance
a. A primary pedestrian building entrance shall be located on one or more primary front facades facing the street and pedestrian way, rather than the rear or sides of the building, and shall be well articulated and visible from the street as described herein. Secondary access points may be located along other facades.
b. In multiuse buildings, each building use and street floor tenant space shall have at least one functional entrance directly visible and accessible from the street. Where tenant entrances are via common lobbies, lobby entrances
3
shall create architectural emphasis through design features such as changes in building plane, step backs, fenestration patterns, balconies, towers, bays, or similar features.
c. If the primary building entrance is not located along the primary front façade then the applicant must demonstrate that the primary building entrance may not feasibly be located along the primary front façade and the primary building entrance shall be located to the side of the building in accordance with the following:
I. Buildings with the primary building entrance on the side shall be visually emphasized to make the entry visible from adjacent and nearby public roadways. Architectural emphasis shall be achieved through design features such as changes in building plane, step backs, fenestration patterns, balconies, towers, building entries, bays, or similar features.
II. Buildings with the main entry on the side shall be accessible by a public walkway connecting the sidewalk along the site’s street frontage to the parking areas.
F. Building Architectural Design Standards: The architectural design standards are
intended to ensure that the size, proportions and design of new or substantially improved buildings create a pedestrian-friendly environment, that is highly articulated as described herein. The visual mass of all buildings shall be de-emphasized through the use of architectural elements including building form, architectural features and materials, in order to reduce their apparent bulk and volume, to enhance visual quality and contribute to human scale development in accordance with the following:
(1) All structures proposed under the same land development application shall consist of
a unified and coordinated architectural theme.
(2) Exterior Building Materials: The predominant material of all facades facing public streets shall be brick, stone, highly textured masonry block, curtain wall, metal panel systems with concealed fasteners, glazed panels, cement-board siding or wood. Stucco or dryvit may be utilized provided it is no more than 20% of non-window facades at the street floor level and no more than 50% of non-window facades above the street floor level.
a. All sides of a building shall be architecturally designed to be consistent with regard to style, materials, colors and details. The architectural treatment of the front facade shall be continuous in its major features around all visibly exposed sides of a building with the exception of parking structures or that portion of a building containing a parking structure. Blank walls or service area treatment of side and/or rear elevations visible from public view shall be prohibited.
(3) Vertical Articulation: Buildings are required to provide articulation on the exterior of any wall surface in order to provide architectural interest and variety to the massing of a building and to relieve the effect of a single, long monotonous wall or roof. Blank facades, without windows or architectural elements to create interest, are prohibited.
a. The massing of any one building wall shall not exceed 50 feet (horizontal dimension) without a vertical articulation along its entire height. Vertical articulation may include a change of building façade plane or material. The depth of change in façade plane for vertical wall articulation shall be a minimum of 2’-0”. Such articulation may consist of building wall offsets,
4
recesses and projections such as bays, balconies, canopies, awnings, pilasters, columns and other similar features.

i. Building corners shall be chamfered at least 10’ from the corner setback. The chamfer shall extend from the ground to the top of the building unless the following features are incorporated:
i. Building corner chamfers may be limited to the street level story only if the portion of building corners above the street level story is visually emphasized through design features, such as step backs, fenestration patterns, balconies, towers, building entries, bays, or similar features.
(4) Horizontal Articulation: Horizontal articulation of the building facade, including changes to the horizontal building plane and/or materials, shall be used to break up the scale of the building facade. Such horizontal articulation may be provided by roof terraces, setbacks or other devices. Horizontal articulation shall emphasize the building base, body and roof/parapet edge.
a. Buildings greater than 40 feet in height shall be designed utilizing a definition of the base, body and roof or parapet edge (or similar designations) as the primary method of defining and relating buildings to one another.
b. The base shall generally be considered the first story of the facade facing a public street, but can vary depending on the overall building height and range from ground plane to the floor line of the third floor in buildings of at least four stories in height. The design of the base should be emphasized through the design, quality and durability of its materials to create visual interest. The transition from the base of a building to the body may be expressed either horizontally, through a shift in the horizontal plane and/or through a change in building materials.
c. The top of a building greater than 40 feet in height shall be architecturally distinguished by providing a visual termination to the facade and interest at the skyline by incorporation of highly detailed architectural elements that are visible from street level.
d. Any building measuring taller than 40 feet in height shall provide an expression line on the wall plane, continuing around all sides of a building above the first or second floor. The expression line may consist of a projecting element, a minimum 4 inches in depth, such as a belt course or cornice as well as a terrace that sets back the walls of the building above the expression line.
(5) Roofs:
a. Rooflines shall be articulated vertically with a change in roof line every 50’. This requirement does not apply to flat roofs.
b. On buildings with flat roofs, all visibly exposed walls shall have an articulated cornice that projects a minimum of 4 inches horizontally form the top of the vertical building wall.

Metal or internally lit non-fabric awnings are prohibited.
d. All roof-top mechanical equipment, including antennas, shall be visually and acoustically screened from view of both the public right-of-way and adjacent properties. Screening may be accomplished by using parapets, walls or roof elements. Such screening shall be integral to the architectural design of the building.
e. Vegetated roofs are encouraged and may be used for stormwater mitigation based on conformance with applicable stormwater regulations.
(6) Proportions of Walls to Openings for Street Level Facades:
a. A street level façade is the building wall or walls where there are primary and
secondary customer entrances and where they are the prominent facades as
viewed from streets or parking areas.
b. A wall to clear window/door ratio of between 2 to 1 and 4 to 1 is required. For
street floor level commercial and retail uses, a wall to clear window ratio
between 1 to 1 and 2 to 1 is required.
c. The maximum length of a blank wall between clear window/door openings
shall be 15’
d. Elements such as pent eaves, pediments, or sills and lintels above and below
windows and doors are required.
